PCB circuit board production process
Cutting - inner layer graphics - lamination - drilling - electroplating - outer layer - solder mask - surface treatment - forming - electrical testing - FQC - FQA - packaging - finished product
Finished Product Inspection (FQC)
purpose:
According to the customer acceptance criteria and our inspection standards, the appearance of the finished PCB board is checked. If there are defects and timely repairs, we guarantee to provide customers with excellent quality control.
FQA
purpose:
According to the IPC standard, the circuit board sent by FQC is sampled and engineered.
Product packaging
purpose:
According to the requirements of MI, the finished PCB board that has passed the inspection is packaged under vacuum and vacuum conditions to prevent the finished PCB board from returning to moisture and convenient for storage and transportation.
